Error message

database.table.operation.failed

What it means

Thrown by DatabaseService.operateTableData when inserting/updating/deleting table data rows fails with any exception. Code 8516, message 'database.table.operation.failed'. It is the catch-all wrapper around batched DML execution after parameter validation has already passed.

Solutions

1. Inspect the log line 'Table operation failed, params={...}' to see the exact request and root-cause stack trace.
2. Run validateParams-equivalent checks client-side: all param keys must match declared field names and required fields must be present.
3. Verify column types/lengths against the current table schema before resubmitting.
4. Retry once in case of transient connection issues; check DB health if it persists.

Example fix

// before
Map<String, Object> params = dto.getParams();
databaseService.operateTableData(dto);
// after: pre-validate against field metadata
Set<String> fieldNames = fields.stream().map(DbTableField::getName).collect(Collectors.toSet());
if (!fieldNames.containsAll(params.keySet())) {
    throw new IllegalArgumentException("unknown fields: " + params.keySet());
}
databaseService.operateTableData(dto);

Set<String> fieldNames = fields.stream().map(DbTableField::getName).collect(Collectors.toSet());
for (Map.Entry<String,Object> e : params.entrySet()) {
    if (!fieldNames.contains(e.getKey())) throw new IllegalArgumentException("unknown field: " + e.getKey());
    if (e.getValue() != null && e.getValue().toString().length() > 65535) throw new IllegalArgumentException("value too long: " + e.getKey());
}

try {
    databaseService.operateTableData(dto);
} catch (BusinessException ex) {
    if ("database.table.operation.failed".equals(ex.getMessage())) {
        log.error("DML failed, params={}", dto.getParams(), ex);
    }
    throw ex;
}

When it happens

Trigger: Calling operateTableData(DbTableOperateDto) with operateType 1/2/3 (insert/update/delete) when the built DML fails at execution: SQL syntax issue in buildDml, value type coercion failure, DB down, duplicate key, or data exceeding column length. Also triggered when validateParams or buildDml throws anything other than the specific field errors.

Common situations: Client sends a string for a numeric column; oversized values for VARCHAR columns; concurrent schema change removed a column; connection-pool exhaustion under load.
